Hello guys

I was wondering if ya can help me with some info. As you may know i have a 2014 sierra on a 100 shot of nitrous. I just purchase the br7ef #3348 spark plugs but dont know what the gapping would be on them, any help i would really appreciate it. Thanks

 

A friend is spraying 150 has gone through several bottles on stock ones and just recently changed to tr7s did not regap truck running with out any hiccups

 

Ok thanks ill look into them and see what my best choice, thanks again

 

Same for my 6.2L. 125 shot... Started small and worked my way up to 125. Was running dry through MAF, but it ran rich without tweaking AFR's. I would be interested in seeing how others have tapped the fuel on the direct injection.

 

Where did you find your spark plugs?
I couldn't find any with the proper depth.

 

If that's how I am reading this, you're about one short away from a firey show.

 

Ill see if I can gets some pics and ill post them I don't know how they did it

 

i learned the hard way on my car projected plugs are a no, no i melted some and in one cylinder as the porcelain exited the valve closed and broke a peace out of it, the main reason for the br7ef is its a non-projected tip so it doesn't get as hot

at the time i was only spraying a 100 shot, with the br7ef plugs i'm @ 150 so far no problems

if your using projected tip plugs i'd swap to non-projected

 

I'm spraying a 150 single nozzle kit on stock plugs and so far no problems. On my second bottle, need to have it refilled

 

plugs are cheap why gamble? sure i got away with it for a few bottles but my luck ran out.
